WebSphere Misconfiguration: Servlets Served By Class Name

Java/JSP

Abstract

O aplicativo é configurado para permitir que o WebSphere atenda Servlets por seus nomes de classe.

Explanation

Permitir que Servlets sejam atendidos por seu nome de classe permite que qualquer invasor que conheça o nome de um Servlet o invoque diretamente, mesmo quando não está mapeado no descritor de implantação do aplicativo.

Por exemplo, considere um aplicativo que contém um Servlet chamado com.ibm.websphere.samples.MyServlet. Quando serveServletsByClassnameEnabled em ibm-web-ext.xmi (para WAS V6 e anterior) ou enable-serving-servlets-by-class-name em ibm-web-ext.xml (para WAS V7 em diante) está definido como true, é possível chamar o servlet solicitando:
http://www.example.com/SomeContextPath/servlet/com.ibm.websphere.samples.MyServlet.

Pior, dependendo da estrutura do carregador de classe do servidor, um invasor pode chamar Servlets de outros aplicativos hospedados na mesma instância do WebSphere.
